Hopefully next spring i will be buying a new scoob however at present i have a few parts for my my00 turbo. i have an sti intercooler, full decat, k&n pannel, vf30 turbo and an ecutek and possibly 550 injectors not yet purchased .Unfortunately i dont wana put 2k into it for a 6 speed
. so if i have it mapped conservatively to circa 300bhp300ftlb would this be safe? and if so do i need the injectors if i dont go above 300? cheers

 

Oh and fuel pump

 

im running 315bhp on my96 wagon on a td05 with 440,s so wouldnt think you would need the 550,s. vf 30 will make 300 easy.

 

i assume a decent fuel pump, turbo, injectors, intercooler and remap rather than just bolt everything together and hope for the best

 

+1. yep he means a well set up engine ie not bolt on the parts and fit a manual boost controller and whack it up to 1.5 bar and blow the engine lol. mine has td05, later spec map sensor, 3 port boost solenoid, 440,s and cat back exhaust and a map by andy f. 315bhp@ 1.3 bar. my injectors are only on 90% duty so a bit of room there but as you can see an easy 300 with no need for the 550,s.

 

Cheers guys. will have to see if the gearbox holds up for a few months :-)

 

from what i read your target of 350 is the limit of the box. ive got a fmic and induction to go on and im hoping to see 340 or so. i might buy a set of 550,s to be on the safe side. drive with a bit of mechanical sympathy and it should be fine.

 

Yeah i figured id get close to 330 with injectors thrown in but figured 300 would be a safer option. the cars mint and never gets thrashed only the occasion blast up the slip road etc. il just have to avoid launching lol

 

Had mine between 300-320 on the standard 98 5-speed box, it was OK until I blew the engine through a combination of heat-soak and having the heads skimmed, with NO thicker gasket.

Live and learn? Sure, but I wish it wasn't so expensive.......

 

i didnt want to go the fmic route but have decided to as its just as much of a pain trying to get a later spec sti top mount to fit as doing the fmic. also the benefit of lower temps to avoid the above mentioned scenario!

 

Next spring is not long to wait really.. My plans were the exact same as you, keep mine for a bit, mod it and then get an STi next year. I've now scrapped all my plans and intend to keep it as is as whatever I spend modding it I won't make a single pound back when it comes to sell.

300+ is a nice figure though! will certainly make a nice fast road car.

 

440cc more then enough for 300bhp, im running 366bhp on 440cc with FPR.

 

anything above 300 on a uk box is pushing it, one missed gear and its all over.

i did mine on the isle of man at 280ftlb lol

 

I know exactly what you mean. apart from yhe ecu im getting off an sn member i only have to pay for the remap as the other parts have been passed on to m. next year im lookin at a wr1 or an early hawk sti. mines mint but modded or nowt a uk2000 will fetch next to nowt which is a shame cos shes been a fantastic car

 

Id guess mines running about 220 with the full decat and my gearbox went on a missed gear change lol but it was a 100k box

 

hahaha, you aint trying unless you miss a gear,, hahahaha

mine look very sorry for itself, great view and weather was good as well lol




then 5am in the mornign loaded to go to the ferry lol

 

Ouch! i was thinking of picking up a 754 but thats more money and i only put the recon box on last year

 

tbh i wouldn't bother, theres little difference in strength between the two. uprated 5 speed or 6 speed are the only real upgrade options

 

i take it thats not on stock fuel pressure bud?

 

FPR is fuel pressure regulator

 

I gave serious thought to putting 4k in my car via a 2.1 stoker and a 6 speed which would save me spending 8-9k on a new car but who can resist the temptation of a nice new motor

 

I resisted newer car lol, spent way to much on mine over the years, yet still on same engine lol, i'm running ppg straightcut box in mine now

to me the newer ones lack the soul of the classics, to heavy and too many gadgets and gizmo's.

 

i knew that bud i was asking if its set at standard fuel pressure or has been raised to flow more.

 

o sorry lol, to get 366 will prob be up, highly unlikley it will flow enough at normal FP level

 

cheers tidgy thats what i was thinking. im asking as im going for another map once the fmic and induction is fitted to (hopefully) see 340 ish as andy f said we could maybe max the td05 around that figure with them fitted. i was gonna source some 550,s but if i can up the fuel pressure to flow a bit more for around the 340 mark then that would be fine.

 

yeah i think many of the new cars lack the rawness and simplicty of the classics. this cars taught me alot about mechanics, they are so easy to work on. i successfully replaced the gearbox on the roadside lol never ever again!!excuse my ignrance but what is a straight cut ppg . ive seen them mentioned but never looked into it

 

mine maxed out at 342 on 440's and standard fpr on a vf34 a few years ago (dropped a touch since then), injectors were maxed which isn't ideal, 550's and fpr would prob be a good way to go. fpr isn;t mega money (£200 for a decent one), so its a usefull supporting mod.

once you start hitting the figures mentioned on a standard engine classic then your well into the area of supporting mods being as important, decent set of gauges to watch oil temps and pressure, nock warning etc Also could idealy do with getting trid of the MAFF, mine blew 2 during mappingbefore gave up and went aftermarket ecu in the end

 

thanks for reply m8, ive got a fpr fitted and apexi ecu an commander so i can monitor air flow and knock etc with that. def in the market for better gauges than the ones i have as andy said the boost gauge wasnt very accurate.

 

300 bhp is easily achievable on a vf 30 and providing you don't launch it all the time, box should be ok.i have been running over 300 bhp 300 lb/ft for over 2 years on my current car and the same on the MY99 car I had before that. You may find your clutch may slip a little when dealing with the extra power , but apart from that it should be ok.
300 bhp in a classic makes a quite rapid car especially compared to 300 bhp in a newage imho.
